THE HAGUE (AFP) - Dutch police have arrested another man in connection with the filming of hundreds of women and girls in the changing room of a prestigious hockey club where three princesses are members, prosecutors said on Tuesday.

Prosecutors said the suspect - along with another man still being sought by police - were in possession of recordings from the changing room that were given to them by a coach at the club, who was arrested last week.

The secret changing room recordings were made at the upmarket HGC club in Wassenaar, an expensive suburb north of The Hague, where Dutch King Willem-Alexander and Queen Maxima's three daughters also play hockey.

The recordings were made between 2006-11 and "the princesses are not on the images", Ilse de Heer, spokesman for the prosecutor's office, told AFP last week.

The public prosecutor said the youngest girls on the images were aged 12. Crown Princess Amalia is now 10.

The 45-year-old coach, identified as Luigi C, has been charged for secretly filming in the club and possessing child pornography. He was identified because his face was recorded when he checked the camera.

The arrest has reawakened calls for youth coaches to require a "certificate of good conduct and morals" from the government, as teachers already do.

Dutch media has said the coach has two previous convictions for exhibitionism and was kicked out of a previous hockey club for inappropriate conduct. Both the coach and the second suspect were arrested on Aug 26, but police have delayed the announcements "in the interests of the investigation".

"There is still no indication that the images have been released on the Internet," prosecutors said. "The investigation is seeking to determine if a wider distribution has taken place."
